| Kit used: | Type of kit used: | ||||||
| Additional information: | The National Park Service had a lab in Colorado perform toxin analysis on tissues from some of the dead coyotes and dogs that had ingested toxic fish along Padre Island National Seashore. The tissues contain high brevetoxin levels, but I do not know the specifics. | ||||||
| Economic losses: | |||||||
| Management decision: | Padre Island National Seashore instituted a temporary ban on dogs from Nov 24, 2009 through mid-or late December. The Texas Dept of State Health Services never opened shellfish season for Corpus Christi or Aransas bays and they remain closed to date. | ||||||
